When i click on certain field, it prompt me an error messages:
1) Fatal error : [MR_NULL_POINTER] Use of NULL pointer on ' '
2) Fatal error : Can not continue in tfxxx2500m200 in DLL: ottstpstandard (ncrs.index2string)[last function:get.argc]

How to get rid of this?

ncrs has to do with the improved record selection (see prog manual on TIV 1075 for example). This did come with ES 8.3.
Is this a customized session? I guess that the Tools Interface Version is set to 1075. Maybe you have to lower the TIV number to its predecessor, 1050, on your script.

Hi there,

Thanks for the information. I tried another way which also can solve the problem by changing the Session Type to Maintain. Then it work fine, no more error.
